“There is no standstill in global warming,” says U.N. weather agency chief Michel Jarraud as he presented the WMO’s annual review of the world’s climate which concluded that 2013 tied with 2007 as the sixth hottest year since 1850 when recording of annual figures began.

“The warming of our oceans has accelerated, and at lower depths. More than 90 percent of the excess energy trapped by greenhouse gases is stored in the oceans. Levels of these greenhouse gases are at a record, meaning that our atmosphere and oceans will continue to warm for centuries to come. The laws of physics are non-negotiable.”
